The Chelsea 892PDFJW-B5AF is a hydraulic hot-shift Power Take-Off from the 892 Series, engineered specifically for Allison 4700 Series transmissions. The 892 Series mounts via a 10-bolt configuration and positions the SAE C output flange at the rear of the transmission, creating better pump clearance between the transmission and frame rail. A one-piece main shaft eliminates the input splines found on extension-style PTOs, while the wet spline output extends PTO and pump shaft life under demanding duty cycles. The series delivers intermittent torque ratings above 501 lb-ft and output power above 56 HP. Common applications include aerial trucks, fire and rescue trucks, refuse trucks, and truck cranes.
